{"id":"CVE-2019-1700","aliases":["EUVD-2019-10257","GHSA-458g-fg5w-22xq"],"status":"published","title":"Cisco Firepower 9000 Series Firepower 2-Port 100G Double-Width Network Module Queue Wedge Denial of Service Vulnerability","description":"A vulnerability in field-programmable gate array (FPGA) ingress buffer management for the Cisco Firepower 9000 Series with the Cisco Firepower 2-port 100G double-width network module (PID: FPR9K-DNM-2X100G) could allow an unauthenticated, adjacent attacker to cause a denial of service (DoS) condition. Manual intervention may be required before a device will resume normal operations. The vulnerability is due to a logic error in the FPGA related to the processing of different types of input packets. An attacker could exploit this vulnerability by being on the adjacent subnet and sending a crafted sequence of input packets to a specific interface on an affected device. A successful exploit could allow the attacker to cause a queue wedge condition on the interface. When a wedge occurs, the affected device will stop processing any additional packets that are received on the wedged interface. Version 2.2 is affected.","severity":{"version":"3.0","score":6.1,"vector":"CVSS:3.0/AV:A/AC:H/PR:N/UI:N/S:C/C:N/I:N/A:H","level":"medium","assessor":"cna","from":"cve"},"epss":{"day":"2026-11-08","score":0.00501,"percentile":0.43166,"model":"v2026.06.15"},"facts":{"in_kev":false,"known_exploited":false,"public_exploit":false,"fix_available":false},"cwes":["CWE-399"],"published":"2019-02-21T21:00:00Z","modified":"2026-06-17T02:29:04Z","products":[{"vendor":"cisco","product":"cisco firepower extensible operating system (fxos)"},{"vendor":"cisco","product":"firepower_9000_firmware"}],"references":[{"url":"http://www.securityfocus.com/bid/107105","tags":["vdb-entry","x_refsource_BID","x_transferred","Third Party Advisory","VDB Entry"]},{"url":"https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190220-firpwr-dos","tags":["vendor-advisory","x_refsource_CISCO","x_transferred","Vendor Advisory"]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2019-1700"},{"url":"https://github.com/advisories/GHSA-458g-fg5w-22xq"}],"sources":{"cve":[{"id":"CVE-2019-1700","title":"Cisco Firepower 9000 Series Firepower 2-Port 100G Double-Width Network Module Queue Wedge Denial of Service Vulnerability","description":"A vulnerability in field-programmable gate array (FPGA) ingress buffer management for the Cisco Firepower 9000 Series with the Cisco Firepower 2-port 100G double-width network module (PID: FPR9K-DNM-2X100G) could allow an unauthenticated, adjacent attacker to cause a denial of service (DoS) condition.
